CULTIVATOR.

To all whom t may concern:

Be it known that I, Fiuinnnicir C. lVAnNE, a citizen of the United States of America, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Cultivators, of which the following is a specilication.

My invention relates to pivot cultivatorsl The objects of my invention are to pro-I vide means. of pivoting the wheels, axles and beams to operate simultaneously and at the same time maintain the same relation between the beams, axles and wheels;

to provide means for actuating'the beams whereby the cultivating devices will dodge any obstruction in their path and make them travel to correspond with any irregularity in the rows; to provide means of automatically exerting a varying downward pressure on the beams to force the cultivating devices into the soil to meet the different conditions thereof; to provide automatic means of assisting the operator in lifting the beams; to provide means of adjusting or regulating the depth of the cultivating devices in the soil; to provide means of attaching the beams tothe cultivator whereby the cultivating devices which are secured to the forward ends of the beams tion to the cultivator when the rear ends or beams are raised thereby balancing the frame and form and simultaneous lateral movement to both plow-beams.

tratcd in the accompanying drawing and described in this specification and particul j cesses to engage the ends of the upwardly larly pointed out in the claims.

raising the beamsl simulf taneously; to provide means of giving unii These and other objects are accomplished by the mechanism Yillusi 5 and 6 are provided with forwardly proseriai No. 636,969.'

nism connected thereto. Fig. 5 is an enlarged View of collars fitted to the axles 'and their connections.

Referring. to the drawings, reference numerals 1 and 2 `indicate axles mad-e substantially Z shape and upon which are mounted the wheels 3 and 4. Vertical sleeves 5 and 6 having transverse journal bearings 7 and 8 are journaled on the axles adjacent to the hubs of the wheels and are rigidly secured and held in a vertical positio-n by the set screws 9 and 10. Shafts 11 and 12 are inserted in the sleeves and their free ends are supported by the washers 13 and 14. Brackets 15 and 1.6 are fitted to the upper extremities of the shafts 11 and 12 and are provided with horizontal portions 17 and 18 into which the axle or shaft 19 is fitted.

In the `journal port-ions 17 and 18, openings 2() and 21 are provided into which collars 22 and 23 are inserted and iitted to the shaft 19 and held in any laterally adjusted position by the set-screws 24 and 25 thereby holding the brackets at different distances from each other and providing means of increasing or decreasing as desired the space or lateral distance between the travel of the beams 26* and 27 which are attached to the brackets 15 and 16 for cultivating rows of different widths.

The forward ends of the beams 26 and 27 are pivotally connected for vertical movement to the inwardly projecting ends 28 and 29 of the axles 1 and 2 and held against lateral movement by the adjustable collars 30-30 leaving the rear ends of the beams free to float or follow the machine when being dragged by the portions 28 and 29 of the axles 1 and 2. The vertical sleeves jecting ledge portions 31 and 32 and retical sleeves 5 and 6 and project inwardly` at right angles to the ledges 31 and 32 and carry tight angle levers L38 and 39 having attached thereto the stirrups 40 and 41. Forwardly projecting brackets 42 and 43 rammed aug. saisie.

well known fastening means. A seat lever 48 is pivotally connected to the seat lever supports by the bolts 49 and 50 which pass through one of a series of apertures 51 which are provided in said lever supports. The seat lever 48 rests upon the top of the axle 19 and is provided with a seat 52 which can be adjusted ina horizontal direction to increase or decrease t-he leverage of the seat lever 48 and to bring the operator closer to i curved rods 65 and 66 are screw-threadedy or farther away from the stirrup to accommodate different sizes of men. vA'clamp 53 fits over the bars comprising the seat lever 48 and prevents the bars from spreading.

Notched segments 54 and 55 are attached to the brackets 42 and 43 and the frame bars 44-44. Operating levers 56 and 57 are pivotally connected to the notched segment by the bolts 58 and 59. The bent ends 60 and 61 of the levers extend in an upward direction as shown in Figs. 1 and 4. The extremities a and b of the bent ends of the operating levers are turned atright angles to the sides of the levers andv pivot pins 62-62 provided with ears 63 and 64 are connected thereto. Curved rods 65 and 66 at one end of their extremities are bent at right angles to the body and inserted in suitable apertures in the ears 63 and 64 thereby pivotally connecting them to' the bent ends a and b of the operating levers.

Connecting collars 67 and 68 provided with bosses having horizontal apertures are fitted and fastened to theends 28 and 29 of the axles. Flat rods 69 and 69 are provided' with hooks 70 and 7 0 on one end to engage the horizont-al apertures in the bosses of the connecting collars and their opposite ends are screw-threaded. The

vthe hooked ends of the lifting rods 78 and 79. The free ends of the lifting rods pass through the ears 80 and 81 of slidable clamps 82 land 83 which are fitted to the beams. A series of apertures 84 and 85 are provided in the lifting rods and washers 86 and 86 fitted thereto and held in place by cutter-pins 8 7 and 88. Coil springs 89 and 90 are interposed between the ears 80 and 81 and the washers 86 and 86 exert a downward pressure on the beams when forced in the soil by the .operating levers.

The free ends of the lifting rods extend .I

ating levers 56 and 57 and are provided with` spring pressed pawls 97 and 98 whichengage the notched segments 54 and to maintain the beams in their idle posltions and to adjust the cultivating devices to regulate their penetration in the soil.

An equalizing bar 99 is mounted on the tongue and held in place for pivotal movenient by the strap 100`and bolts 101 and 102. The equalizing bar pivots upon the bolt '103. Hitch bars 104 and 104l lare connected to the equalizing bar as shown or in any otheil well know manner. bar 105 is pivotally connectedto the free ends of the hitch bars and the opposite ends` are connected to the journal bearings 7 and 8 by the bolts 106 and 106. Braces 107 and 107 are attached to the ears 31 and 32 on one end and the. opposite ends are secured to the axles. 1 and 2 by the through-going bolts or rivets 108 and 108 to maintain t-he vertical pivot sleeve at right angles wit-h the yaxles 1 and 2. The Shanks 109 of the cultivating devices are securely clamped to the beams by the clamps 1010-110.

. The operation is as follows: lVhen it is desired to cultivate the soil, the operating levers 56 and 57 are manipulated in a vertical direction upon their pivotal supports. The forward end of the beams being connected to the operating levers, a vertical One end of the draft movement is imparted to the beams increasing or decreasing the depth or penetration of the lcultivating device in the soil. It will, of course, be understood that the beams under normal condition ride substantially on a plane with the cultivator. The operating levers 56 and 57 are provided with releasing and 'locking levers 95 and 96 to maintain* the operating levers in their proper relation to the soil and can be adjusted to increase or decrease the depth of the cultivating devices in thesoil or in maintaining them in idle position for transportation, corner turning or the like as shown in Fig. 4. The wheels and beams are simultaneously `turned to dodge a crooked row of corn or the like and obstructions by the operator placing his feet on the stirrups 40 and 41 and pressing forward. When one stirrup is pressed forward the other is moved in the rearward or in the o posite direction.- as they are connected toget er by the link bar The vertical sleeves. 4 and 5 are connected Cil to the axles 1 and 2 and to the right angled levers 38 and 39, the wheels 3 and 4 and the beams 26 and 27 move -in a lateral direction at the same time and maintain the same relative position to each other.
